Has anyone in the community seen any progress in the
buffer_append_space() vulnerability, which sets the buffer's
allocated int when it isn't allocated?

The last process that I used last September was to use data compression
to crash buffer_append(). When this was done, the data would cause a
crash before the space was allocated. At that point I had "deer in the
headlights"

If anyone has any ideas or knows of a poc in regards to this
vulnerability, I would greatly appreciate it.
